SPECIFICATION formingpart of Letters Patent No. 727,648, dated May 12, 1903. Application filed February 28, 1903- Serial No. 145.555. (No model.)

T at whom it may concern:

Be it known that I, JOHN A. LIEB,Jr., a citizen of the United States, residing at Newark,

in the countyof Essex and State of New J ersey,

have invented and produced a new and original Improvement in Interchangeable Initial Letters or Insignia for Finger-Rings,&c. and ldo hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to numerals of reference marked thereon,.which form a part of this specification.

The objects of this invention are to facilitate able initial letters or insignia and in the ar-.

rangements and combinations of parts, all substantially as will be hereinafter set forth and finally embraced in the clauses-of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a perspective View of a ring having my improvements. Fig. 2 is a plan of a box-like part on which a top plate having an initial letter may be placed; Fig. 3 is a longitudinal section of said box-like part. Fig. 4 is an end view of the same. Fig. 5 is a sectional viewof said top plate and initial letter. Fig. 6 is an inside plan of the top plate'. Fig. 7 is an" end view of a certain keeper-plate; Fig. 8 is a top or outside plan of the top plate and initial letter. Fig. 9 is a planof the keeper-plate, and Fig. 10 is a sectional view of the same. Fig. 11 is a sectional view of the top plate, initial letters, and keeper-plate in operative relation to the box-like part; and Fig. 12 is an end view of the top plate and initial.

Fig. 13 is another plan of the keeper-plate, showing the side which lies toward the bottom of a certain boxlike part; and Fig. 14 is a perspective view of one of a pair of springs on an enlarged scale. V

In said drawings, loindicates a finger-ring having a box-like-part 16 at one side, which latter is open at the top, as shown in Figs. 2 and 3, to receive a top plate 17, said box being preferably curved, asin Fig. 4, to conform to the finger and the 'top plate being correspondingly curved, as indicated in Fig. 12.

Suitable bearings 18 are provided to support the top plate,and these'are preferably the ends of springs 19, soldered or otherwise fixed upon the inside walls of the box, as indicated in Fig. 3,said springs being free from said walls intermediate of their ends for purposes hereinafter described. Said top plate 17 is perforated to receive the notched pins 20,extending inward from the initial letter or-insignia plate 21, to which they are rigidly fixed, said pins extending to or near to the bottom of the box-like part, where they are notched or recessed to receive the edges of a keeper-plate 22. Said keeper-plate 22 is also curved, as in Fig. 7,

and conforms to the bottom of the box and is adapted to slide on said bottom a limited dis- .tance. It is provided with oppositely-extend- 8o ing fingers 23, Fig. 9, which impinge at their extremities upon the side walls of the box,

and thus any lateral movement thereof is prevented. Said fingers 23 underlie the springs 19 or extend between said springs and the bottom of the box, and the springs 19, intermediate of their ends, are bent so as to hold the keeper-plate with more or less security against longitudinal movement.

The central part of the keeper-plate is cut 0 out or slotted toreceivthenotchd end of one of the pins 20, and at one end of the slot 24 and at the end of the plate opposite the handle 25, as at 26, the said plate 22-is reduced in thickness to form lips adapted to 5 enter the notches 27, Fig. 5, of the pins. Thus by pressing the keeper-plate 22 longitudinally against the pins 20 the said keeper-plate 22 enters into locking relation to said pins and holds the latter and the initial-plate 21 theretoo to attached fast upon the box-like part 16, and said initial-plate in turn holds the top plate 17 securely in the top opening of the box.

The finger extension or handle 25, extending longitudinally from the keeper-plate, projects through an opening in the end of the box, as in Fig. 11, and is thereat provided with a lug 28, adapted to engage the edge of the bottom of the box and limit the inward movement of the handle and its plate 22, the extremity of said lug 2S lying flush with the concave outer surface of the bottom of the box, thereby filling the perforation in the box and giving a proper finish to the appearance of the same. The lug 28 permits a finger-nail, blade, or other implementto push the handle and its keeper-plate outward to release said keeper-plate from the notched pins 20, so that the initial or insignia plate 21 may be released and withdrawn from the box-like part and another substituted therefor.

The springs 19, disposed at the opposite longitudinal side walls of. the box, are bent, as in Fig. 14, to form shallow receptacles 29 for the oppositely-projecting fingers 23 to hold the keeper-plate in looking position; but the fingers 23 are preferably slightly rounded at their points of engagement, so that when the keeper-plateis pushed longitudinallyin either direction there will be an easier disengagement or locking of the parts, as will be understood.

To detach the initial letter or insignia plate for the purpose of interchange, the keeperplate is pushed at the lug 28 by the fingernail or by a blade or implement and the notched pins 20 are released, as described. The top plate is thus free to be withdrawn from its seat and the insignia-plate 21 is withdrawn from the top plate. A second insigniaplal e may then replace the one thus removed and be fastened in place by the keeper-plate operating as described.

Having thus described the invention, what I claim as new is- 1. The combination with the box-like part, having springs at opposite side walls, of a perforated top plate, an insignia-plate with notched pins, and a keeper-plate engaging the springs and held thereby into locking relation with the pins, substantially as set forth.

2. The combination with the box-like part having springs therein at opposite side Walls, the said springs being fast to provide seats for the top plate, and loose at parts to engage a keeper-plate with a resilient pressure, of a top plate, an insignia-plate with notched pins, and a keeper-plate engaging said springs and pins, substantially as set forth.

3. The combination with the box-like part having bent springs therein, each having a receptacle 29, intermediate of its end and fastened at its opposite ends to a wall of the boxlike part, a top plate, pins extending inward therefrom, and a keeper-plate having arms extending oppositely to engage the receptacles of the spring and having a handle extension extending through the Walls of the boxlike part, substantially as set forth.

4. The combination with the box-like part and top plate having notched pins extending inward therefrom, of springs having their opposite ends fixed to the said box-like part and serving as seats for said top plate and having their intermediate portions free to engage a keeper'plate, and said keeper-plate, having opposite extensions engaging said springs and having lips engaging said notched pins, substantially as set forth.

5. The combination with the box-like part and top plate having notched pins extending inward therefrom, of springs having their opposite ends fixed to the said box-like part and serving as seats for said top plate and having their intermediate portions free to engage a keeper-plate, and said keeper-plate having opposite arms extending between the springs and the bottom of the box-like part, and having lips engaging said notched pins, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of February, 1903.
